Draw the graph of y = 6x
by filling in the table below.
X| y = 6x
----------
-2|
-1|
0|
1|
2|
Domain = ?
Range = ?
all polynomials are defined for every real number. So, the domain is all reals.
Since a sloping line extends forever in both directions, what's your best guess as to the range?
Surely you can fill in the table. Just multiply x by 6, right?
